S. et al, 2023). As our understanding of the relationship between plants and humans continue to evolve, it is becoming increasingly clear that this relationship is essential not only to our physical survival but also to our psychological and social well-being, as well as the longterm health and sustainability of our pluricultural systems.…”

People-plant interaction studies the complex interactions that exist between humans and the natural environment, particularly plants; it is a thorough research that covers a wide range of views, including ecological, cultural, and psychological aspects. People-plant interaction, at its foundation, investigates how humans use plants as resources and imbue them with cultural and spiritual values, plants have provided humans with food, medicine, and shelter for millennia, and they have considerable cultural and symbolic importance in various nations and cultures. Furthermore, research on people-plant interactions emphasizes the numerous ways in which exposure to plants might promote human health. Exposure to nature, particularly plants, has been demonstrated in studies to help decrease stress and boost productivity. Indoor plants have been shown to enhance air quality and provide a more pleasant environment for humans to work and live in. With our planet's serious environmental issues, understanding the intricate interactions between humans and plants is more crucial than ever. Human-caused environmental changes, such as deforestation, pollution, and climate change, have a significant influence on the natural world, including plants.

AimsA comprehensive understanding of the genetic variation of walnuts (Juglans regia and J. sigillata) in the Himalaya and its potential drivers are essential for the conservation and sustainable utilization of these plant genetic resources. In this study, we aimed to uncover the genetic landscape of walnuts and potential drivers in the Himalaya for better utilization, awareness, sustainable management and conservation of the extant genetic resources of walnuts in the vast Himalayan landscape.LocationThe Himalaya biodiversity hotspot.MethodsA total of 1410 wild or feral walnut trees from 65 populations of J. regia and J. sigillata across four countries in the Himalaya were collected. The genetic diversity, population structure, hybridization and gene flow were thoroughly investigated based on the chloroplast genome and 31 nuclear microsatellite markers. The patterns and drivers of the walnut genetic landscape were further explored.ResultsWe detected three genetic groups of J. regia (JR1, JR2, JR3), one of J. sigillata (JS) and two hybrid types (JR1 × JS and JR3 × JS) of walnut in the Himalaya, with the western Himalaya identified as the genetic diversity hotspot of J. regia. The spatial genetic pattern of the J. regia was significantly influenced by geographic and climatic factors. Human‐mediated dispersal probably promoted the hybridization and gene introgression between J. regia and J. sigillata, which reshaped the genetic landscape of walnut populations in the Himalaya.Main ConclusionsThe extant genetic landscape of walnuts in the Himalaya was driven by natural and anthropogenic forces. Regarding conservation, the western and eastern Himalaya are the genetic reservoir of J. regia and J. sigillata, and hence, pure individuals should be urgently protected from frequent hybridization and introgression. In addition, we propose the utilization of natural hybrid resources coupled with new breeding techniques that combine genomic and phenotypic data.

“…Agricultural biodiversity can be increased by either increasing the portfolio of cultivated crops, thus reversing the current path toward narrowing agricultural crop production [1], or increasing the number of available varieties through decentralized participatory plant breeding [19]. The Centre for Sustainable Development and Environment (CENESTA) used this strategy by implementing a participatory barley breeding program that allowed the identification of a number of lines superior to the widely grown improved variety Sararood-1 [20].…”

Barley is an important feed crop in Iran and is threatened by an increased frequency of drought. Increasing diversity in the form of evolutionary populations (EPs) and mixtures is one strategy to increase the resilience of crops. Four barley EPs, which have evolved in different locations over 7 to 10 years from the same original population, were evaluated for agronomic trait and stability together with two landraces, and one improved variety for three cropping seasons in four locations. Modest but significant differences were found only for plant height with a range of less than 4 cm. Stability, measured with cultivar superiority, as well as environmental variance and reliability measures generally indicated a superior stability of EPs—with two of them ranking first and second for grain yield reliability—but also differences between the EPs. The effect of recurrent droughts on the diversity within EPs is discussed as a possible explanation for the lack of divergent evolution. The seed management of Eps, including seed exchange between farmers, is suggested as a possible strategy to avoid the reduction in diversity within populations. Future research will address the nutritional value of the EPs, which is often quoted by sheep owners as superior to commonly grown varieties.
